一、发布镜像到DcokerHub
- 首先需要去https://hub.docker.com/网站注册属于自己的账号；
- 确定新注册的账号可以登陆；
- 在我们的服务器上提交自己制作的镜像文件。
[[email protected] ~]# docker login --help
Usage: docker login [OPTIONS] [SERVER]
Log in to a Docker registry.
If no server is specified, the default is defined by the daemon.
Options:
-p, --password string Password
--password-stdin Take the password from stdin
-u, --username string Username
[[email protected] ~]# docker login -u jzyue
Password:

[[email protected] ~]# docker push jzyue/tomcat01:1.0 #提交自己的镜像到dockerhub上
The push refers to repository [docker.io/jzyue/tomcat01]

常见报错
在提交的时候提示没有tag标签
[[email protected] ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
tomcat01 latest 66fd9bfabe82 13 hours ago 695MB
[[email protected] ~]# docker push jzyue/diytomcat:1.0
The push refers to repository [docker.io/jzyue/diytomcat]
An image does not exist locally with the tag: jzyue/diytomcat
这里需要对镜像打一个标签
[[email protected] ~]# docker tag 66fd9bfabe82 jzyue/tomcat01:1.0
[[email protected] ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
jzyue/tomcat01 1.0 66fd9bfabe82 13 hours ago 695MB
二、发布镜像到阿里云镜像仓库
1.登陆到阿里云(https://account.aliyun.com)；
2.找到容器镜像服务；
3.创建命名空间；
4.创建容器镜像仓库，仓库类型：公开代表所有人都可以看到；私有只有自己可以看到；
5.进入到仓库，根据阿里云的操作指南来实际操作一下。
[[email protected] ~]# sudo docker login [email protected] registry.cn-beijing.aliyuncs.com #登陆到阿里云
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See

Login Succeeded
[[email protected] ~]# docker images #查看镜像
REPOSITORY TAG IMAGE ID CREATED SIZE
jzyue/tomcat01 1.0 66fd9bfabe82 14 hours ago 695MB
[[email protected] ~]# docker push jzyue/tomcat01:1.0 #推送镜像到阿里云仓库
The push refers to repository [docker.io/jzyue/tomcat01]
cd2c8c332d4e: Pushed
097d8efb1a01: Pushed
fc617a256ca8: Pushed
4de30c3ac6c2: Pushing [============================================> ] 340.6MB/384.5MB

具体详细操作参考阿里云操作指南
